Assuming the '2' recur to infinity.

In which case it should be written as 0.1222.... Note three or more dots after the last decimal digit. This is the mathematical notation for recurring to infinity.

Then let P = 0.12222....

Then 10P = 1.2222...

100P = 12.2222....

Subtract

90P = 11

(Note the recurring '2' subtract to 'zero'.).

P = 11/90

This will Not reduce any further. , and is the answer!!!!!
